OK, let me summarize and explain:
I chose the place for Djenne because of 3 arguments:
1. Djenne is on a hill and gives +1P long-term and more security.
2. Djenne has 3 resources long-term, which makes it a good production city
3. Because I get 2 more citys from Sury, I have time to choose good longterm-placement and don't need to hurry. Hurrying would mean to get a second settler faster, but getting a second settler would mean 5 citys all-together, which will cripple my finances, because except of my capital no city can contribute to commerce for now.
I understand your hint, that you would say, fast starting production in the 2nd city is everytime more important than choosing a good long-term good placement. Right? Is it still the case, when there are 2 more citys elsewhere?

Second topic I am interested:
Trade route by sailing or by roads? Building a road needs 12-14 turns for the worker, while building a mine needs just 6 turns and the worker is free again to chop. So in my opinion it would make more sense to get the trade routes with sailing (12 turns, maybe less, with the new cities), for which I can start with the lighthouse directly. In this situation here I will have a massive amount of border cities, which make sailing and Great lighthouse a good goal.
Are my thoughts not correct? Maybe you can help me in calculate it, why roads are really necessary. For now it seems I need neither fast movement nor a trade route by road.
1.4. The attack (2nd part)
I would chose to go for
Fishing -> Sailing -> Stone Masonry -> Agriculture
and Great lighthouse, because another civ could get the oracle before I can start it. After stone masonry I would decide from the new situation.
Capital: Worker -> Library -> Lighthouse -> Great Lighthouse (start with overflow and whip the end)
Djenne: Monument -> 2x WB (1 for scout) -> Library
Worker: Finish mine SW from Djenne, after that prechopping at capital, start building roads to silver
I go for attack Surys cap on the fastest way:
Round 86 before attack. Combat seems harder than I thought at first:
My skirmisher with star and 25% bonus against archer vs. his undeveloped archer: 4.40 : 7.20
Hmm... that was closer than I thought: Lost 3 skirmishers. I think he has no BW, so he cannot whip an archer. Let's try to get his second city with the remaining troops, but but first of all taking the one worker north. I need to chop a monument as soon as possible.
Questions: When obertaking a city, it revolts. Does it need troops there?
